Has anyone compared the commish schedules: Bundled vs Unbundled at IB? I wonder which one would be better. Thanks.
Do some calculations. unbundled is most likely cheaper if you trade a tremendous number of contracts. Try comparing the commision on 1 contract using both methods, then compare it to trading 100 or 1,000 contracts. Then you will have your answer. You can always calculate the break-even point and go from there.
I have found the unbundled is better for me as I add liquidity in over 90% of my trades. IB customer service has been a very frustrating experience for me though so keep that in mind as you shop brokers.
